FLUSVHING APPARATUS.

SPECIFIQATION forming part of Letters Patent No. 743,184, dated November 3, 1903. Application tiled October 21, 1902. Serial No. 128,180. `(No model.)

T cr/ZZ wir/077e t may concern:

Be it known that I, HORACE FALK NEU- MEYER, a citizen-of the United States, residing at Macnngie, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Flushing Apparatus, of which the following is a specication.

The present invention relates to flushing apparatus for closets,vand more particularly to that class in which the mechanism is operated by the depression of the seat.

One of the objects of this invention is to provide practical valve mechanism of an extremely simple character that is not liable to become leaky or inoperative and is so arranged that the parts may readily be reached, removed, and repaired or renewed by persons other than expert plumbers.

The preferred embodiment of the invention is fullyillustrated in the accompanying drawings, whereinmm Figure 1 is a view in elevation of the apparatus when applied to a closet. Fig. 2 is a vertical sectional view, on an enlarged scale, through the mechanism. Fig. 3 is a transverse sectional view taken on the line a: a; of Fig. 2. Fig. 4 is a detail sectional view taken on the line y y of Fig.' 3.

Similar numerals of reference denote corresponding parts in all the figures of the drawings.

In the embodiment shown a bowl is employed, to which is connected the usual soilpipe 11, said bowl having a hinged seat 12 arranged thereon. These parts may be of any desired construction and in themselves form no part of the present invention. Beneath the bowl is arranged a vault 1.3, within which the mechanism is housed.

Suitablysupported within the vault 13 is the valve mechanism, which is constructed as follows: A body 14 is employed havingadepending stem 15, which is'attached, by means of a base 16, to a support 17, fastened to thesoilpipe. This body is provided with an interior chamber 18, at one end of which is arranged an inlet-opening 19, while the other end is provided with a discharge-opening 20, the portions of the body about these openings being formed into suitable valve-seats. A supply-pipe 21 is connected with the inlet end of the body by a suitable coupling 22, While a discharge-conduit 23 is in like manner connected to the discharge end of the body. The top of the body is in the form of a threaded nipple 24, having an opening 25 therein,which opening communicates with the chamber 18. To this nipple is secured a pipe 26, the other end of which is attached to the lower end of a reservoir 27, arranged within the vault 13, as clearly shown in Fig. l, said reservoir being air-tight. A valve-stem 28 is slidably mounted in the chamber 18 and has its ends projecting beyond the same, being provided with annular flanges 29 and threads, as 30.

Upon these ends are arranged valves 31, con' structed of rubber or other compressible material and held in place by ianged nut-s 32. The valves are arranged to alternately close the inlet and outlet openings of the chamber 18 upon the movement of the stem 28. To secure this movement, an actuating-spindle 33 is journaled in the body and extends across the chamber between the valve-stem 28 and the upper opening 25, the inner end of the spindle being located in a seat 34, the other end projecting through a suitable journal-opening 35 and having a reduced outer terminal 36. In order to prevent leakage at this point, a packing-cap 37 is secured about the projecting end of the spindle. The valve-stem 28 is provided in an intermediate portion with a socket 38, and the actuating-spindle has a threaded opening 39 therethrough, said opening and socket being arranged to aline with the upper opening 25 Aot' the body. A connectingfinger 40 is threaded through the spindle and has its lower end engaging in the socket 38, as shownin Fig. 2. This linger is preferably provided with4 a tool-receiving slot 41 in its upper end, and thus by removing the pipe 26 access can be gained to the finger, so that it may be removed from the spindle through the upper opening 25 of the body. The outer reduced terminal of the spindle 33 is made angular, and to the same is attached a lever 42, one arm of whichis longer than the other arm. Upon the long arm is slidably mounted a Weight 43, normally held against movement by a set-screw, as 44. The other arm is provided in its upper edge with a notch, as 45, and a stirrup 46 is arranged upon this latter arm, said stirrup being provided with an opening to receive the same, the upper IOO wall of the opening tapering to a knife-edge, as 47. The stirrup is held in place by a split key 4S, passed through the free end ofthe lever-arm. This stirrup is secured to the lower end of an upright operating-rod 49, extending through a suitable guideway 50a. formed on the bowl and constituting a support for the seat 12, which is normally held raised a slight distance from the upper edge of the bowl by means of the weight 43, as will be readily understood. The discharge-conduit 23, connected with the discharge end of the body 14, is also attached to an upright coupling 50, and to the upper end of said coupling is secured a conduit 51, leading to the upper end of the bowl. This coupling 50 has a reduced vent-opening 52 in its lower end, and a pipe 53, secured to said lower end, leads to the soil-pipe, as shown in Fig. 1. The vent 52 is controlled by a plug or cone Valve 54, arranged exteriorly of the coupling 50 and having a stem 55 passing through the vent, said stem carrying at its upper end a horizontal disk 56, that is arranged transversely of the passage-way. This disk under normal conditions rests upon an annular shoulder 57, arranged within the coupling and having slots 58 through the same to permit the escape of water. A pressure-reducing disk 59 is secured across the channel, being interposed between the ends of the pipe 51 and the coupling 50, said disk having an opening 60 therethrough that is of less diameter than the diameter of the passage-way. The upper end of the pipe 51 passes through the edge of the bowl, and to its inner end is secured a iiushing-jet 61 in the form of a cap having in its end wall a transverse slot 62, the portion of the cap on one side of said slot being inset, as shown at 63. The jet, furthermore, has openings 64 in its side walls. Under ordinary conditions the inlet 19 is closed by its valve, because of the arrangement of the weight 43, which likewise 4elevates the seat 12 in the manner shown in Fig. 1. When said seat is depressed, the rod 49 will be forced downward, thus turning the actuating-spindle 33 and opening the inlet to the body, at the same time closing the outlet. Water will therefore pass from the supplypipe through the pipe 26 into the reservoir until the pressure of the air Within the same equals the pressure of the water-supply. As soon as the seat is elevated the Weight 43, acting on-the lever 42, will again close the inletvalve and open the outlet, whereupon the air under pressure in the reservoir will force the water from said reservoir through the various conduits to and through the flushing-jet. During its flow, however, it will strike the disk 56 and elevate the same, thereby moving the valve 54 to closed position and cut-ting oif the vent. As soon as the flow of water has ceased the disk and valve will again drop, whereupon the vent will be opened and the water remaining in the pipes and reservoir will gravitate through said vent and into the soil-pipe, so that no standing water will remain in the apparatus.

It will be seen that the various elements of which this apparatus is composed are eX- tremely simple and that they may be readily reached for the purpose of repair or renewal. For instance, if it is desired to remove the valves and operating mechanism therefor it is only necessary to uncouple the several pipes from the body, whereupon the screw-finger may be removed through the opening 25 while the valves are exposed. Attention is also invited to the construction of the connection between Vthe operating-rod 49 and the lever 42. This structure is of such a nature that it cannot readily become inoperative, and there is practically no frictionbetween the parts.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and .minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
